Description
Technical field
This utility model relates to the technical field of mechanical water pump, especially relates to a kind of water-hammer arrester.
Background technology
Water hammer also known as water attack, water or other liquid in course of conveying, due to valve be turned on and off suddenly,
Water pump stops suddenly, suddenly opens and closes the reasons such as stator, makes flow velocity that change suddenly to occur, and pressure produces big simultaneously
The phenomenon of amplitude fluctuation.Owing to tube wall is smooth, follow-up current are under the effect of inertia, and waterpower is rapidly reached
Greatly, and produce destruction, here it is " water hammer effect " in the middle of hydraulics, namely positive water hammer.On the contrary,
The valve closed is throwing open or after feed pump startup, also can produce water hammer, is negative water hammer, but before not having
Person is big.Because turn on pump, termination of pumping, controlled valve are excessively quick, the speed of water is made to occur drastically to change, the most prominent
The water hammer that so termination of pumping causes, can destroy pipeline, water pump, valve, and cause water pump to invert, and ductwork pressure reduces
Deng.Water hammer effect has great destructiveness: pressure is too high, will cause rupturing of pipe, otherwise, pressure mistake
The low collapsing that can cause again pipe, also can damage valve and fixture.In the extremely short time, the flow of water
Violent to metered flow from zero.Owing to fluid has kinetic energy and a certain degree of compressibility, therefore when extremely short
In the great variety of flow will cause the too high and too low impact of the pressure to pipeline.
The most traditional water-hammer arrester, including cylinder, the bottom of cylinder uses the side of the mode bottom being spirally connected
Formula is fixed, and the opening of cylinder is bolted with joint, and joint is provided with three-way valve, is provided with plug in cylinder.This
Plant water-hammer arrester and can reach to eliminate the effect of water hammer effect to a certain extent, but conventional for a long time, by
In the impact of water hammer effect, cause the sealed bottom of cylinder to reduce, and the management and control of three-way valve operation also shows
Obtaining the most loaded down with trivial details, work efficiency is extremely low, and the accessory needed is the most, and structure is the most extremely complex, gives and produces
Processing exerts a certain influence.
Summary of the invention
The deficiency existed for above-mentioned prior art, the purpose of this utility model is to provide a kind of production and processing pole
It is convenient and swift, and uses operation convenience extremely, and sealing property is high, eliminates the effect pole of water hammer effect
Good, the simplest water-hammer arrester of structure.
For realizing above-mentioned purpose, this utility model provides techniques below scheme:
A kind of water-hammer arrester, including body, is provided with axially displaceable plug in body, body is integrated
Making and have one end open, the port of body is fixedly connected with joint, joint is provided with external screw thread.
This utility model is further arranged to: the bottom of described body is arranged with groove, groove to port direction
Middle part be convexly equipped with projection to the opposite direction of port.
This utility model is further arranged to: described projection is hemisphere jut.
This utility model is further arranged to: the port of described body is provided with necking end, necking end and body
Port between connected by arc-shaped transition section, necking end and joint are fixing to be connected.
This utility model is further arranged to: be sequentially provided with logical by splice port to body direction in described joint
Kong Yi, through hole two and through hole three, the port of through hole three and jointing communicates.
This utility model is further arranged to: the aperture of described through hole one is more than the aperture of through hole three, through hole two
By through hole one to through hole three direction decreasing pore size, the maximum diameter of hole of through hole two is equal with the aperture of through hole one,
The minimum-value aperture of through hole two is equal with the aperture of through hole three.
This utility model is further arranged to: the aperture of described through hole three is less than the aperture of the port of jointing.
This utility model is further arranged to: the lateral wall of described plug is provided with at least one seal groove, close
Sealing ring it is provided with between sealing groove and the tube wall of body.
This utility model is further arranged to: be provided with air or noble gas between described plug and its bottom.
This utility model is further arranged to: described body is red copper body.
By using technique scheme, the technique effect that this utility model is reached is: by improving body
Structure, uses integral type to make so that the stress of product itself strengthens, and sealing property is then the most corresponding to be promoted,
Eliminate the loaded down with trivial details joint with three-way valve simultaneously, directly use simply with male connection, connect
Fast and easy, production and processing is the most convenient and swift, and uses operation convenience extremely, and sealing property is high,
Eliminating the works very well of water hammer effect, structure is the simplest.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Fig. 1 is sectional structure schematic diagram of the present utility model.
